Jenny, the eight year old neighbor next door, had just come home from school, she noticed the note on the door and took it with her to her room, she was alone in the house at the time, her parents would be back in a half hour. She put down her back pack and read the note aloud. "I wish that I had the exaggeration of the ideal body of the opposite sex, in it's adult form, with my original head, and that no one would notice this other than me and the writer of this note."
Jenny looked up at her mirror for a minute, the little girl sitting on her bed staring back at her didn't seem any different, she wondered who would write such a thing. When she looked down again the note was gone, and a strange feeling was starting in her crotch. Her mother had taught her about sex, and what it does and the difference between boys and girls, she was determined that her daughter wouldn't make the same mistake so many girls did. She looked down at her crotch and notice a bulge swelling larger by the second. She poked it.
The bulge responded by getting tighter and larger until it exploded out of her panties and lifted her skirt, a massive penis, a foot and a half long, throbbing with power thundered out of her small body, she screamed at the sight. Girls weren't suppose to have a penis! How is this happening she panicked in her mind as the penis swelled, and balls slid out of her small woman hood making it disappear as the scrotum formed. She didn't have long to think as she felt her shoes get tighter, her feet exploded in size and girth, finally stopping at a mens size fourteen.
She tried to lift her new huge feet, but she couldn't muster the strength, her lower legs started to tingle as to her horror they started to grow longer, and thicker, ripping what was left of her socks. Her lower legs stopped at a foot and a half tall, and a half foot thick with pure muscle. By this time her penis had stopped growing at a full three feet, with balls the size of cantaloupes her upper legs soon followed as they throbbed and swelled with her hips getting larger. Her legs finally stopped at the full three feet of length to the hip a man's should be, but they measured a massive foot and a half thick at the thigh. Her growth stopped for a moment.
She tried to take in what she, now he was seeing, her once tiny petite legs and woman hood were now replaced with this massive powerhouse of man hood and legs that would make body builders envious. She was taken away by arousal in her new parts and she couldn't help herself. She placed her tiny hands on her new massive member, she couldn't even wrap around her new members foot thick girth. She rubbed it, teasing her member not even thinking about what she was doing until she cam. The cum blasted all over her floor and onto the bottom of the mirror.
She didn't have enough time to think as her chest started tingling and she looked up to see it swelling larger, her spine popping as it got bigger. Her blouse ripped open revealing abs that were rock hard and pecs exploding with growth, her upper body swelled to proportions not unknown to a Clydesdale horse. She flapped her tiny arms, which wore the remnants of her blouse as she tried to see over the massive pecs that she just acquired her neck followed swelling to massive size, making her little girl head seem ridiculous on this Juggernaut of a body. Her hands exploded with growth as her arms grew longer, massive mountains of muscle grew in place of her once dainty arms.
She now was the owner, proud or scared, of this massive manly body, she started to cry in her little girl voice as her mass thundered when she stood up and ran out of her room, she thundered down the stairs to meet her mother at the door, built like a tank, and hung like an elephant.
